CVE-2026-90775

Estado: Pendiente de análisisAlta (7.1)—

PostGIS address_standardizer through 3.7.0 fails to validate the Weight parameter from caller-supplied rules tables before using it as an array index. Attackers can craft malicious rule rows with out-of-range Weight values to trigger out-of-bounds reads in the load_value array, causing the PostgreSQL backend process to crash and terminate all cluster sessions.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
